Overview
A buyer who wants a light cordless saw for small cutting jobs gets this Craftsman, which runs from a battery and spins at the listed speed. The cutting part is high speed steel and the weight is low for a cordless tool.
The reason to buy is the low weight and cordless use for light cutting. The limitation is the lack of any listed size, battery or blade type, so what it cuts and how long it runs are unclear.
Who it's for
Home owners with Craftsman batteries who want a light cutter for small jobs will find the weight easy to manage. Anyone cutting thick material needs a tool with a larger listed capacity.
Pros and cons
- High rated speed
- High speed steel part
- Battery not named
- Dimensions not listed
Performance notes
A light tool is easier to control for overhead and one-handed cuts but has less mass for heavy material. Listed speed and capacity set the cutting range, and battery capacity limits runtime. The listing names no blade, so cut quality cannot be judged.
